CVE-2026-108625 in JeecgBoot
Summary
by MITRE • 10/11/2026
JeecgBoot through 3.9.5 contains a missing authorization vulnerability that allows low-privileged authenticated users to modify message push records by calling PUT /sys/message/sysMessage/edit. Attackers can submit a request body naming any sys_sms record id to overwrite its title, content, receiver address and send status without ownership checks.

The vulnerability identified in JeecgBoot versions up to 3.9.5 represents a critical failure in access control mechanisms within the application's message management module. Specifically, this is an insecure direct object reference (IDOR) flaw located at the PUT /sys/message/sysMessage/edit endpoint. The core technical issue stems from the absence of proper authorization checks when processing requests intended to update existing system SMS records. In a secure implementation, any operation that modifies sensitive data or configuration settings must verify that the authenticated user initiating the request possesses explicit ownership rights over the target resource or holds an administrative role with sufficient privileges. However, in this vulnerable version, the backend logic accepts the identifier of the sys_sms record from the client-side request body without validating whether that ID corresponds to a message originally created by or assigned to the current session's user context.
This architectural deficiency allows low-privileged authenticated users to escalate their effective permissions significantly. By manipulating the input parameters in an HTTP PUT request, an attacker can specify arbitrary identifiers for system-wide SMS records. These records often contain critical communication data intended for specific recipients within the organization. The vulnerability permits the overwriting of key fields including the message title, content body, receiver address, and send status. This capability effectively neutralizes the integrity guarantees provided by the messaging subsystem, as any authenticated user can alter communications destined for other users or administrative accounts without detection through standard permission logs alone.
The operational impact of this vulnerability is severe due to its potential for social engineering and disruption of business operations. An attacker could modify the content of a message intended for an executive or IT administrator to contain malicious instructions, phishing links, or misleading information designed to trick the recipient into taking harmful actions such as revealing credentials or executing malware. Furthermore, altering the receiver address allows for message redirection, potentially exposing sensitive internal communications to unauthorized external parties if the attacker can specify an email domain they control. The ability to change send status may also be leveraged to create false logs of successful deliveries or suppress notifications that might otherwise alert administrators to ongoing attacks or system anomalies.
From a classification perspective, this vulnerability aligns with CWE-284 Improper Access Control and more specifically CWE-639 Injection of Critical Data into an External Resource via Indirect Reference Manipulation. In the context of the MITRE ATT&CK framework, this behavior corresponds to T1078 Valid Accounts, as it relies on legitimate credentials, and potentially T1564 Hidden Files and Directories if used to conceal malicious activities within log files by manipulating status fields. The exploitation requires only basic authentication, making it accessible to a wide range of threat actors who have obtained valid user accounts through phishing or credential stuffing attacks.
Mitigation strategies must focus on implementing robust server-side authorization checks for all state-changing operations involving shared resources. Developers should ensure that the PUT /sys/message/sysMessage/edit endpoint validates the ownership of the sys_sms record against the authenticated user's identity before processing any updates. This can be achieved by querying the database to confirm that the creator_id or assigned_user_id matches the current session's user ID, rejecting requests where this condition is not met with a 403 Forbidden response. Additionally, implementing role-based access control (RBAC) restrictions at the controller level for administrative endpoints would prevent low-privileged users from accessing sensitive management functions entirely. Regular security audits and static code analysis focused on object reference validation are recommended to detect similar patterns in other modules of the JeecgBoot framework before deployment.
